Subject: [PATCH 5/6] ENH: Fix pointer size determination for cross build
|
|
|
|
Using `sys` to ask about the build Python is hostile to cross
|
|
building because it is very hard to replace the sys module with one
|
|
that gives info about the target system. On the other hand, the
|
|
sysconfig data can be replaced by setting _PYTHON_SYSCONFIGDATA_NAME.
|
|
So instead of using `sys.maxsize` to determine pointer size, use
|
|
`sysconfig.get_config_var("SIZEOF_VOID_P")`
